[texts]Rapid Intensity Degradation in InGaSb/InAlGaSb Quantum Well Lasers - M. Yin and R. Jones
As a factor to limit higher lasing temperature, the rapid lasing intensity degradation in mid-infrared InGaSb/ InAlGaSb quantum well (QW) laser diode has been found and analysed. Due to higher resistance, defects, produced and developed by driving current in p-cladding layer, destroy lattice structure and make the lasing intensity decay. SEM result confirms the defects appeared in p-cladding layer and induced by driving current...

[texts]BOREAS TE-9 NSA Photosynthetic Capacity and Foliage Nitrogen Data - Dang, Qinglai
The Boreal Ecosystem-Atmospheric Study (BOREAS) TE-9 (Terrestrial Ecology) team collected several data sets related to chemical and photosynthetic properties of leaves in boreal forest tree species. This data set describes the spatial and temporal relationship between foliage nitrogen concentration and photosynthetic capacity in the canopies of black spruce, jack pine, and aspen located within the Northern Study Area (NSA)...

[audio]2.57 Nano-to-Macro Transport Processes Fall 2004 - MIT OCW
This course provides parallel treatments of photons, electrons, phonons, and molecules as energy carriers, aiming at fundamental understanding and descriptive tools for energy and heat transport processes from nanoscale continuously to macroscale. Topics include the energy levels, the statistical behavior and internal energy, energy transport in the forms of waves and particles, scattering and heat generation processes, Boltzmann equation and derivation of classical laws, deviation from classica...
